" MCDONALD, OF BAR/R9151, VTISCONSIN sAm'rAn-Y Bnusn Application filed. November 15, 1929. Serial No. 407,536.

This invention relates to a sanitary brush.

The object of my invention is the construc-' tion of a? simple and efficient brush to be used especially by barbers in the treating of" the hair of human beings, or for scalp treat-1 ment, as each case or customer desires.

Another ob ect of my invention is the construction of avery' efficient brush which is of a fountain type, and which can be easily manipulated by the operator for most 'advantageous results.

, brush.

. A still further object of my invention is the construction of a simple and eflicient brush, the-parts of which can be quicklyseparat'ed for disassembled for cleaning the brush; when the parts are cleaned, they can likewise be quickly assembled, whereupon the brush will be ready for use. II

' With'the foregoing and-other objects view, my invention comprisescertain novel constructions, combinations and arrange- Inentsv of parts as will be hereinafter, fully described, illustrated in the accompanying drawings, and more particularly pointed out in thelappended claims.

perspective view of a top plan view'of the screen 1 v as steppingupon integral'handle thereof. The handle '2 is of suitable shape to be easily grasped by the operator and said handleconstitutes a reservoir for-the liquid to be used in the brush. The handle is filled at 3 when the stopper or cap lis removed. Atthe innerend of the .han'dleis arigid closure tit 5 upon which is placed one endof theap'e'rtured rubber tube 6 (Fig. 2) The tube 6 is suitably perforated to allow well-spreading of the liquid, as in; di'cated in Figure 4. I

,The"outwardly-bulging body casing 1 is: Y

ment, and the grooves 8 are likewise;

into grooves 8, from the outer end of the brush casing 1 (Fig. 2) and the frame 10 of the brush head 11 is slid into the grooves 7 from the outerend of casing 1 towards its inner'e'n'd." The frame 10 of the brush head is provided with a rearwardly extending protecting tongue 12, which guards the rubbertube 6 near the tit 5. 1 The rubber tube 6 isadapted tolie on screen 9 and the liquid screenonto the brush head.

The brush head 11 omprises said frame 10 with itslongitudinally extending bristleholdin'g bars 13 and reinforcing V-shape bar inforcing bars make a ver'y durable and 'efii provided interio'rly on vits sides with grooves I screen frame 9, with the mesh center, is slid cient brush head. The bristle s17 are. very strong, in fact, thefirstftest may beas severe the bristles without doing them any; injury.

To preventv accidentalmovement or displacement I I I side edges of the frame 10, locking or brakof'the'brush head,I form, on the" shallow sockets 19 formed in the grooves 7.

'Also the same kind of lugs can be formed on V the screen, Fig. 18, for preventing accidental displacement of the screen off the casing 1. It is to be understood that both the brush head and the screen will be slid on and oif of the casing 1, at the will of the operator, but

' by employing the shallow sockets 19 and the bra-king lugs 18, the parts will not-rattle nor will they work loose or be accidentally disassembled. As shown by dotted lines A, Figs. 4 and 10, the casing 1 and the body 28 have a springy or expansible action.

In the top of the handle 2 near the inner end of the casing 1, I form an elongated aperture Extending through this aperture is the rearwardlybxtending flat; stem 21 of the control device 22. The control device includes said stem 21, presser plate 23 and thumb-plate grip 2d. The presser plate; 23 is curved. transversely to fit upon therubber tube 6, and has a slight Sl-l-Gllllg movement thereon as hereinafter explained. The flat stem 21" is integral with the top of the presser 1 plate, this stem a straight rear edge and apeculiarly curvedfront edge '26, for

the purpose hereinafter specified. The grip- 2 1 is preferably serrated upon its outer face.

to better accommodate the thumb on finger of the operator. By pressing inwardly upon the grip or plate-grip, the operator can force the liquid forward into the rubber tubing 6, similar to a pumping action, or if he desires,

he can press strongly inward upon-the grip 24k causing the pressure plate 23 to collapse the tube 6, closing the same, for preventing liquid passing. from the reservoir-handle into tube 6 if it is so desired. W hen the operator presses upon'the grip 2 and slightly forwardly upon the tube 6,

his also causes the curved front edge 26 of stem 21, to be pressed'agamst the inner end of'slot 20, but owing to the peculiar .curva:

' ture-of the'front edge 26, there will be no bindingaction, as the resiliency of the'rubber' tube 6 is such as to force or cause'th'e stem 21 to IlClGOLllIWiLIGllY, when manual pressure is sufficiently removed from grip 24; to perinitthis action. In other words, thestrokeof'the' control device 22 isforward, causing the straight rear edge 25 toride freely over therear end of slot 20, whereas the front curved edge 26 willride' under the front-end of slot 20, ready to slide-back over this end as the pressure of the operators-thumb or finger varies upon the control device.

. In F gure 7 the cover 27 is placed upon the body 28 (Figal0) of the casingand screws 29 are used to fasten the coverin place' The screen shown in Figures 7 and-8 is also fastened in place by screws 30, Fig; 7.

My simplebraki'nglugs and sockets hereinbefore described for the embodiment shown :3 in Figures 1 and 2 lock the "brush headand the tendency isto causepressur-e plate 24 to move downwardlyscreen in position, whereas in the embodiment shown in Figure 7, I employ screws for holding the parts assembled. The brush head shown in Figure 10 is of the same gen-. eral construction as thevbrush head shown in Figure 4.-. The control device shown in Figure 7, for this embodiment, is of the same structure as shown in the embodiment de-' 'picted in Figures 1 to 5.

The shampoo unit or brush head in Figures 11 and 12 comprises a' frame IO, similar to the frame illustrated in Figure 6,with the rubber teeth 31 depending upon the bars of the frame '10. This shampoo unit or head (Figsll and 12) can be easily and quickly substituted for the bristle typehead, and is V admirable for use in shampooing."

As hereinbefore. mentioned,'the dotted lines A, Figs. 4: and 10 indicate that the'casing 1 and the body 28 can sufficientlyexpand to allow theseating of the lugs 18 int-he. sockets 19, or the unseating of same when it is desired to separate the parts of the brush. 7

- It will thereforebe seen that I have produced a fountain type brush, excellent for use in shampooing, and which comprises,

handle. Further, I have shown means for efficiently lockingthe parts together against accidental displacementor disassembling. I have shown an ellicient control device for assisting in pumping the. liquid from the reservoir-handle to the head of the brush or eiiicientl'y preventing the liquid from flowing, as the operator desires.- J
